Description

Verfahren zur Verbesserung der Eigenschaften von Leimen 1)as Patent 765 cggr hat ein Verfahren zur Verbesserung der Eigenschaften von tierischen Leimen oder Leimen auf der Grundlage von Kunstharzen:, z. B. Hanistoff-Formaldehyd-Harzen, zum Gegenstand, das dadurch gekennzeichnet ist, daß dem wäßrigen Leim Lösungen bis zu etwa 20°/o des Leimgewichts an Faserhtofteni zugefügt werden , in Form eines wäßrigen Faserschleimes aus nahezu bis zur Sbrukturlosigkeit naß zermahlenen Fasern.Process for improving the properties of glues 1) as patent 765 cggr has a process for improving the properties of animal glue or glues based on synthetic resins: e.g. B. Hanistoff formaldehyde resins, to the object, which is characterized in that the aqueous glue solutions up to be added to about 20% of the glue weight of fiber clay, in the form of a Aqueous fiber slime made from fibers which have been ground wet to a point where they are almost completely devoid of structure.

Nach einem eigenen älteren Vorschlag wird dieses Verfahren zur Herstellung von Wasserglasleimen verwendet.According to its own older proposal, this method of manufacture is used used by water glass glue.

Bei dliesen beiden älteren Verfahren *ird- die die Eigenschaften der Leime. verbessernde Faser, z. B. Papier-, Holz- odor Lederfaser, zweckmäßig in einem Holländer mit Steinzeugmahilwerk derart vermahlen, daß die Faserstoffe in einem gallcrt.artigen Schleim aus sehr fein zerteilten Fasern oder Faserresten übergeführt werden. Dieser Faserschleim wird dann mit dem Leim vermischt.In these two older methods, the properties of the Glues. improving fiber, e.g. B. paper, wood odor leather fiber, useful in one Dutch with stoneware mill in such a way that the fibers are ground in one Gall-like mucus from very finely divided fibers or fiber remnants transferred will. This fiber slime is then mixed with the glue.

Diese Arbeitsweise hat verschiedene Nachteile, die vor allem darin liegen, daß der Faserschleim, der durch Naßvermahlung von Fasern in Gegenwart von Wasser erhalten wurde, sehr viel Wasser, z. B. 9o o/o und; darüber enthält, so daß diese große Wassermenge dem Leim durch Trocknung oder Verdampfung wieder entzogen werden muß. Dieser Wasserentzug, insbesondere durch Verdampfung, beeinflußt nachteilig die Natur derschleimig gemahlenen Fasern.. Die Fasern gehen teilweise in Lösung, so daß die Faserstruktur des@ Leimes geschwächt wird. Außerdem wird der Leim selbst durch den langen Verdampfungsprozeß geschädigt.This way of working has several disadvantages, the main one being that lie that the slime produced by wet grinding of fibers in the presence of Water was obtained, a great deal of water, e.g. B. 9o o / o and; about it contains so that this large amount of water is withdrawn from the glue by drying or evaporation must become. This removal of water, in particular by evaporation, has an adverse effect the nature of the slimy ground fibers .. The fibers partially go into solution, so that the fiber structure of the glue is weakened. Also, the glue itself is damaged by the long evaporation process.

Es wurde nun gefunden, daß die Eigenschaften von Leimen durch Zusatz von Faseirstoffen in Form eines wäßrigen Faserschleimes aus naß zermahlenen Fasern in noch höherem Maße unter Vermeidung der geschilderten Nachteile verbessert werden können, wenn man die Faserstoffe trocken oder in Gegenwart geringer Mengen Wasser vorzerkleinert und die Naßvermahlung in dem zu verbessernden flüssigen Leim selbst durchführt.It has now been found that the properties of glues by adding of fiber materials in the form of an aqueous fiber slime from wet ground Fibers can be improved to an even greater extent while avoiding the disadvantages described can if you dry the fiber or in the presence of small amounts of water pre-crushed and the wet grinding in the liquid glue to be improved itself performs.

Die Vermischung des Le.im@s. mit den Faserstoffen wird durch diese Art der Vermahlung viel inniger, als wenn der für sich erhaltene flüssige Schleim mit dem Leim verrührt wird. Durch die Vermahlung der trockenen oder fast trockenen Faser mit dem Leim wird die Faser vollkommen mit Leim durchtränkt und die Verbesserung der Eigenschaften des Leimes, insbesondere seine Klebefähigkeit, nach dem erfindungsgemäßen Verfahren noch mehr gesteigert. Außerdem entfällt bei diesem Verfahren die Trocknung oder Verdampfung der Mischung. Beispiele i. 6o kg feuchtes Spaltleimleder (tierische Haut) werden in einem Steinzeugholländer mit iooo kg 3oo/oiger Brühe aus, Haut- oder Knochenleim so lange vermahlen, bis die Hautfaser sich :in, schleim@iger Form im Leim zerteilt hat. Man erhält einen gebrauchsfertigen Leim, dessen Eigenschaften gegenüber dem Ausgangsleim wesentlich verbessert sind. 2. 5o kg Buchenholz, das durch alkalische Kochung aufgeschlossen worden ist, werden im Steinzeugholländer mit iooo kg 5oo/o,igem wäßrigem Harnstoff-Formaldehyd-Leim so lange vermahlen, his die Holzfaser in einen schleimigen Zustand übergeführt ist und sich gleichmäßig mit dem Leim vermischt hat. Das Faser-Leim-Gemisch besitzt für die Verleimung wertvollere Eigenschaften gegenüber dem verwendeten Ausgangsleim.The mixing of the Le.im@s. with the fiber is through this Kind of grinding much more intimately than if the liquid mucus preserved for itself is mixed with the glue. By grinding the dry or almost dry Fiber with the glue, the fiber is completely soaked with glue and the improvement the properties of the glue, in particular its adhesiveness, according to the invention Process increased even more. In addition, this process does not require drying or evaporation of the mixture. Examples i. 60 kg of damp split glue leather (animal Skin) are made in a stoneware dutchman with 100 kg of 3oo / o solution of broth, skin or grind bone glue until the skin fibers are in, slimy form divided in the glue. A ready-to-use glue and its properties are obtained are significantly improved compared to the original glue. 2.5o kg of beech wood, that has been digested by alkaline cooking, are in the stoneware Dutchman ground with 100 kg 500 / o, aqueous urea-formaldehyde glue for so long, his the wood fiber is converted into a slimy state and is evenly distributed mixed with the glue. The fiber-glue mixture is more valuable for gluing Properties compared to the original glue used.

3. 2o kg lufttrockene Cellulo,se werden in einem Steinzeugholländer mit iooo kg Wasserglas 40° Bz so lange vermahlen, bis die Cellulose sich in schleimiger Form .im Wasserglas zerteilt hat. Man erhält einen sehr zähflüssngien, außerordentlich bindekräftigen Leim.3. 20 kg of air-dry cellulose are put in a stoneware dutchman Grind with 100 kg water glass 40 ° Bz until the cellulose becomes slimy Has divided the shape in a glass of water. You get a very viscous, extraordinary strong glue.

PATENT CLAIM: Process for improving the properties of animal, vegetable or artificial glue. Originated by the addition of fibers from almost structureless fibers, characterized by the fact that the milling of the fibers until the formation of the structureless fiber slime takes place in a dry or slightly moist state in the presence of the liquid glue to be improved.
